Damage and fracture resistance of continuous fiber-reinforced cross-ply composites.

Fracture Mechanics of Fiber-Reinforced Composites

Quantitative understanding of the parameters which control composite fracture is imperative to the implementation of fail safe design and inspection of critical load bearing structures. For isotropic materials, fracture is essentially controlled by a single parameter, e.g., the fracture toughness or the stress-intensity factor. This one dimensional nature lends itself to experimental quantifica...

Non-destructive Characterization of Ply Orientation and Ply Type of Carbon Fiber Reinforced Laminated Composites

As the fuel efficiency of vehicles is being increased over the next decade due to both consumer demand and regulations, several automobile manufacturers are incorporating fiber-reinforced composites into their product line due to their high strength to weight ratio. While the fiber-reinforced components are lighter than the traditional aluminum and steel components, the processing and repair of...

Blast resistance of unidirectional fiber reinforced composites

Three-dimensional transient deformations of a laminate comprised of several unidirectional fiber reinforced layers perfectly bonded to each other and subjected to a blast load are analyzed by the finite element method with an in-house developed, verified and fully validated code with rate-dependent damage evolution equations for anisotropic bodies. The continuum damage mechanics approach employ...

Investigation of Mode I Delamination Resistance in Inter-ply and Intra-ply Hybrid Composites Reinforced with Basalt/Nylon Woven Fabrics

Due to their sensitivity to impact-induced delamination, woven fabric reinforced polymer composites have limited practical applications. Hybridization of polymer composites has been proposed as a solution to this problem. In this study, the effects of fiber reinforcement type, hybridization method, plies stacking sequence and loading rate on mode I delamination behavior of pure basalt, pure nyl...
